How can I protect myself on a public hotspot?

Episode 1240 (1:01:26)

Doug from Alabama

Doug does a lot of traveling on the road and he uses a open Wi-Fi hotspots a lot. He's worried about the security of using those hotspots, though. Leo says that using a Virtual Private Network (VPN) is a good solution, as it burrows a secure tunnel through the hotspot so that all of his data is encrypted. He'd be totally safe and secure. The downside though it that using a VPN will slow him down a lot, and they are a challenge for some to set up. And the reality is, more and more of what he'll be doing online is encrypted anyway. There are some things that he can do to protect himself in the open, such as turning on second factor authentication for his email accounts.
